EYELETING-(MACHINE.

no. 915,996. I

Be itknown that I, JAMES E. MCINTIRE, a

- citizen of the United States, residing in .Dor-

chester, county of Suffolk, and State of Mas sachusettahave invented an Improvement in eleting-Machi'nes, of which the following escr i ption, in connection with the ac companylng drawing, is a specification, like characters on the drawings representing like a. i y This invention has for its-ob ect the roduction'of a novel machine for 'pun'e ing holes in and setting eyelets in stock.

My novel machine comprisesa su port for the head of the eyelet, sald support I aving a central 'member rigid with relation thereto,

and serving as the male member of a punch, and also to retain the e 'elet on said su port and act as a guide for t e female mem er of the punch, said' female member havin an upsettin shoulder to act on the end oi the shank 0 the eyelet as the exterior of said female member on slidim over the male member enters the shank of the eyelet.

Prior to my invention many eveleting machines have means for punching holes in stock andkthereafter the part of the stockis laid over one member of the eyelet setting devices and the eyelet is set. a

" Figure 1', in side elevation, illustratesan eyeleting machine embodying my invention; ig. 2, a plan View below the dotted line :r,

-Fig. 1; Fig. 3 shows the male and female members of the punch and setting members separated with an eyelet sustained on the e elet support in position to be clenched on the stock after the same has been provided with ahole; and Fig.4! shows the eyelet as set. 1

' In the drawingl'h represents the framework of the mac me. l he forwardly proecting portion A of the frame has'a raised ledge A forming, as shown, an inte ral por: tion ofthe framework and provi ed wlth four bosses a bored through axially to the bottom of the portion A. Each boss; re

ceives a sto -screw a' that enters a groove b in a leg b", tliere being four'such legsdepending from a table or stock-support B, the ends of said legs resting each on a s )ring [1 controlled as to its pressure by an sustained on a screw if, said springs actin non mally to raise the table, as shown in ig. 1. This table B is rovidedwith an opening (not shown) for tlie passage ofthe punch in Specification of Letters Patent. Application filed June 2,,1906- Serial No. 319,818,

eters, the smaller bore 0 entering thebottom of the larger bore 0'. In these boxes I locate the male punching member d, it having an enlargement d? at its lower side that is sustained by the bottom of the bore 0. The member (1 is surrounded by a tubular portion (6 having its upper end sha ed to resent a coneaved portion to sustain t 1e he or en' lar ed end-of the eyelet e, the bore through said tubular portion being largest at its upper end-or of a diameter-in excess of the diameter of the male punching member,-as shown at d, to leave a space to be entered by the free end of the female punch member f as the latter in co-acting with the other parts of the apparatus completes the setting of the eyelet, as shown in Fig.4; of the punch iscomposed of a pieccof stee havin a boss depending froma [settin shoul erf, there being a central hole throu the punch that is a fit to the exterior of t e male portion (1, the upper end of the female The female portion 6' ortion'having a screw-thread to be screwed "sage g for the discharge of punchings formed at each operation of punching a hole in the stock and setting an eyelet therein. 7

'ihe end of the male-portion has a reduced extremity 2 to facilitate the entrance of said male portion into the endmost eyelet e' of the racewayie. The central passage f of the female portion is of such diameter as to fit 9 the exterior of the male portion (1 and as the thin circular end of the lenmle portion passes below the shoulder 2 near the end of the male )orticn said end and shoulder act to out a hole in the stock, thepunching being forced into the central passage '4 ol' the female por-' tion, and as'the relative iosition of the two portions are cl'uinged the fennrle portion slides over the male portion WlllOlLlt hugs closely, and the tapered extoriorol' the endol the female iortion enters the space bet .een

the end of t 1e shank of the eyelet and the male portion, said" space being shown in Fig. 3, and acts' gradually to expand said small end, so that the end of the shank of the eyelet asst meets the concaved setting shoulder f, overhangs that end as the larger end of the eyelet rides on the concaved end of the sustainer d, the tapered part of the female portion enter- ,ing the space (I as the tubular eyelet sustaining portion and the shoulder of the female punch act finally to fully set the eyelet.

' The eyelets to be set are deposited in bulk in a hopper It provided with a suitable agitator, which may be a brush it, on a rock-shaft 7L2 that may be oscillated in any usual manner through a link h attached to an arm h" of said rock-shaft.

The side of the frame has a guideway m that receives a slide m having a depending cam-plate m pivoted thereon by a stud screw in, said cam-plate sustaining the race ay 2. The cam-plate has a projection a tapered at its underside, at 8, and having a heel 10. The framework has a rock-shaft it provided at one end with an arm 11, having an inwardly projecting stud n said rock-shaft being surrounded by a spring n that acts normally to turn said shaft until said arm meets the stop a". The plunger g is moved up and down by a pin g that enters a slot g in a lever g pivoted at 9 to frame-work A, said lever having a pin that enters a slot g in a raceway moving lever p pivoted at p to framework A and having at its lower end a stud 12. As the upper end of the lever g is turned to the left from the position Fig. 1 to depress the plunger, the stud 12, as shown in Figs. 1 and 2, will meet the left hand end of slide m and push the same toward the right in the guideway, such movement of the slide causing the cam-plate m to be moved to the right against the spring 15 (see Fig. 2), and with it the raceway, the latter leaving its endmost eyelet on the male portion at. As the female portion descends the heel 10 of the earn-plate in its movement meets the stud a of the arm, turning the same in a direction to coil the spring a and by the time that the female portion of the punch completes the setting of the eyelet, as shown in Fig. 4, the slide and raceway complete their movement to the right, and the toe 13 of the cam-plate passes beyond the stud n letting the spring 15 move the shaft until the arm meets the stop a". Now as the lever is moved backand cam-plate are moved to the left, the in- 1t and turningsaid plate about the stud screw m and lifting the free end of the raceway so that it is moved forwardly said free end with its eyelets will be raised above the end of the stationary male portion d of the punch, stretching the spring 16, and the heel 1.0 of the cam-plate passes said stud, said spring 16 acts, the cam-plate drops, and the end most eyelet of the raceway is deposited on the stationary upper end of the male portion let sustaining member (1. 'lhc upper cud of the male mcmberd of the punch has around it a projection 17 integral therewith and the stock when laid on the table when struck at its upper side as the female portion of the punch descends and meets the stock, forces the under side thereof on to said projection, the latter stretching the stool; and forcing a part thereof into the opening of thc prolongation thereof stretching the stock bcforclhc end of said prolongation passes the shoulder at the upper end of the portion d to punch the hole in the stock, the stock in a furthcr descent of the female portion bcin forced on to the shank of the cyclct surrounding the upper end of the male portion. The projection 17 forms a tapering hollou in thcstoch and by stretching the stock insures a holc of the pro )er shape and size to receive readily the eyelet.
